CHARLES BEYER, OF CEDAR RAPIDS, IOWA.

BLOW-STACKER.

Application filed February 24, 1914.

b all ywhom it may concern Be it known that I, CHARLES Bryan, citizen of the United States, residing at Cedar `Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Blow-Stackers, of which the following is a specication, reference being had to the accompanying drawings.

This invention relates to certain improvements in blow stackers, such as are now generally employed with separators ,or threshing machines; and the object of the invention is to provide an attachment to be employed in connection with the discharge end thereof having novel and improved means whereby the discharge through such stacker may be controlled in such a manner as to permit the requisite deposit of the straw with resultant injury thereto being reduced to a minimum.

The invention also has for its object to provide an attachment of this general character having novel and improved means whereby expansion is permitted the air in order that the force thereof may be materially reduced so that the fall of the straw, after being emitted from the stacker, is substantially free of the action of the air whereby such straw drops naturally and without injury upon the stack therebeneath.

'Ihe invention consists in the details of construction and in the combination and arrangement of the several parts of my improved blow stacker whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully vdefined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein-l Figure 1 is a view in side elevation of an attachment constructed in accordance with an embodiment of my invention; Fig. 2 is a longitudinal vertical sectional view taken through Fig. 1 at substantially the transverse center thereof; and Fig. 3 is a sectional view taken substantially on the line 3 3 of Fig. 1, looking in the direction of the arrow.

As disclosed in the accompanying drawings, 1 denotes the upper extremity of a Specification of Letters Patent.

Serial No. 820,706.

blow stacker of a threshing machine or the like which may be of any ordinary or preferred construction andconnected with the upper extremity thereof is the improved attachment which, as herein set forth, comprises a body 2 of predetermined dimensions provided at its lower extremity with the clamping or engaging means 3, herein disclosed as in the nature of a split ring, suitably connected to the body 2, as is believed to be clearly shown in the accompanying drawings. The under portion of the body 2 is open, as shown at 4L, whereby it will be perceived that the air, as soon as it is emitted from the stacker l proper, is capable of expansion whereby the force thereof upon the straw being conveyed thereby through the stacker is released so that the contact of the straw with the buffer 5 intersecting the body 1 is such as to substantially assure no injury to the straw. Adjacent its outer end, the upper portion of the attachment is also open, as at 6, so that practically none of the force of the air acts upon the straw in forcing it downward upon the stack. Projecting upwardly at opposite sides of the opening 6 are the plates 7 herein shown as integrally produced with the body 2 in a manner which is believed to be self-evident, and the inner vertical edges of such plates are provided with the alined openings 4f* whereby an adjustable mounting is afforded for the cross arm 8, such arm being provided at its extremity with the trunnions 9 adapted tok project through alined openings 7 whereby such cross arm is capable of rocking movement.

I The cross arm 8 has securedy thereto the upper extremities of the tines 10 of the buffer 5, such tines being substantially L- shaped in form, with the heel portion thereof formed into a convolution or coil 11 whereby the depending or stem portions 12 of the tines are disposed on diverging planes, which arrangement has been found impractice to best accomplish the functions desired of the buffer 5. Suitably connected to the upper portions of the convolutions or coils 11 is a second cross arm 14 having its opposite extremities formed into trunnions 15 and looselyy engaged with such trunnions 15 are the extremities of the yoke sections 1G pivotally united at their' inner ends by the pintle 17, such pintle lalso serving as a mounting for the clevis 18, to which is suitably connected a {iexible member 19 whereby it will be readily perceived that the buffer 5 may be conveniently and readily adjusted to a required angle relative to the discharge end of the stacker 1, or more particularly the adjacent portion of the body 2. In order that the pull afforded by the flexible member 19 may be assured of proper result upon the buffer 5, it has also been found of advantage to employ the additional yoke sections 2O in pivotal engagement with the trunnions 9 of the cross arm 8 and with the pintle 17 which unites the adjacent extremities of the yoke sections 16.

Suitably supported by the forward portion of the vertically disposed plates 7 and in close proximity to the upper and forward edges thereof is a shaft member 21 projecting beyond the opposite sides of such plates, as indicated at 22, and pivotally engaged with such projected or extended portions 22 are the arms 23 projecting upwardly from the hood or deflector plate 24 intersecting the upper end of the body 2. The hood or deflector plate 24 is adapted to be adjusted in unison with the adjustment of the buffer 5 and in order that this may be accomplished, the free extremities of the arms 23 have pivotally engaged therewith the links 25, the opposite lextremities of such links being provided with the elongated slots 26 through which project the trunnions 15 of the cross arm 14 resulting in an operation which is believed to be self-evident.

The normal position of the buer 5 and the hood or deflector plate 24 is substantially vertical and this normal position is maintained through the medium of the contractible members 27 herein disclosed as coil springs, each of such springs having one extremity suitably connected, as at 28, to the hood or deflector plate 2%1, while the opposite extremity thereof is suitably connected, as at 29, to the body 2. The hood or deflector plate 24- serves to deflect the dust yand chaff which is forced through the tines 10 of the buffer 5 which is believed t be self-evident. it

F rom ,the foregoing description it .is thought to be obvious that an attachment for blow stackers constructed in accordance with my invention is of an yextremely simple and comparatively inexpensive nature and is particularly Well adapted for use by reason of the convenience and facility with which it may be applied in operative position upon an ordinary blow stacker and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. An attachment of the character described comprising a body having its upper portion open adjacent an end thereof, plates projecting upwardly at opposite sides of the opening, a cross arm rotatably mounted in such plates, la plurality of tines substan tially l.shaped in form secured to such cross arm, the heel portions of such tines being coiled, a cross arm secured to the coils of the tines, and means coacting with such last named cross arm for adjusting the position of the buffer.

2.,An attachment of the character described comprising a body having its upper portion open adjacent an end thereof, plates projecting upwardly at opposite sides of the opening, a cross arm rotatably mounted in such plates, a plurality of tines substantially .L-shaped in form secured to such cross arm, the heel portions of such tines being coiled, across arm secured to the coils of the tines, means coacting with such last named cross arm for adjusting the position of the buffer, a deflector pivotally connected with the body and intersecting an end thereof, and an operative connection between the second named cross arm and the deflector whereby such deflector will be adjusted in unison with the adjustment of the buffer.

3. An attachment of the character described comprising a body having its upper portion open adjacent an end thereof, plates projecting upwardly at opposite sides of the opening, a cross arm rotatably mounted in such plates, a plurality of tines substantially L-shaped in form secured to such cross arm, the heel portions of vsuch tines being coiled, a cross arm secured to the coils of the tines, means coacting with such last .named cross arm for adjusting the position of the buer, a deflector pivotally connected with the body and intersecting an end thereof, .an operative connection between the second named cross arm and the defiector whereby such deflector will be adjusted in unison with the adjustment of the buffer, and contractible means coacting with the body and the deflector serving to maintain the deflector and the buffer normally in one position.

ln testimony whereof I hereunto affix my signature in the presence of two witnesses.
